Re: [Virtuoso-users] Installing DBpedia datasets

Hi Alex, The 1000 row limit is in place on the public DBpedia instance we host to prevent inadvertent or otherwise misuse of the service by users attempting to run queries returning large number of rows (potetially millions) which would degrade the performance of the server. Best Regards

Re: [Virtuoso-users] Installing DBpedia datasets

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Hugh, Thanks for the recommendations. However, getting hold of a 8GB 64-bit Linux machine or anything of the like is not practical (or affordable) for me. A public SPARQL endpoint may be the solution, if I can only get around the restriction of 100

Re: [Virtuoso-users] Installing DBpedia datasets

Hi Alex, I would definitely say your Windows Vista 32bit machine is under resourced for hosting a fully loaded DBpedia instance in Virtuoso, being basically a desktop spec machine. I would recommend a higher spec. machine and a Server based OS ie Windows Server 2003 or 2008 or Linux which

Re: [Virtuoso-users] Installing DBpedia datasets

Hi Alex, I would say the "out of memory" errors in the installer log are a bit more than minor, as the system would appear not to have the resources for hosting the datasets being loaded. What are the details of the machine you are attempting to host your DBpedia instance on: 1. What is

Re: [Virtuoso-users] Installing DBpedia datasets

Hi Alex, What are the minor errors you indicate having occurred ? The SPARQL query timeout is set to 60 by default, thus you might want to try increasing the MaxQueryExecutionTime paramter in the [SPARQL] section of the dbpedia.ini file which controls the timeouts and restart the server.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Hugh, The installation seems to have completed fine now (a few minor errors), and I've just tested the SPARQL endpoint in the browser, but the server seems to be complaining. S1T00 Error SR171: Transaction timed out SPARQL query: ... I received
